I bought these for the inside of my cabinet door. But my cabinets have inset panels and I was afraid the screw would come through. I put them in my studio on the side of a large cupboard. They hold all the wrap and bag boxes and work great and are a very nice quality. To install all you need is a screw driver. 

Pros: Hold 4 boxes of wrap or bags - good quality - Easy to install 
Cons: None
